What is causing British Columbia's salmon die-offs?

[link to www.theglobeandmail.com] "In the early 1900s, the Fraser River had annual runs estimated at 100 million sockeye. Now it seldom sees more than 10 million. In 2009, it fell to one million. So the decline over time is dramatic, persistent and threatening."

Greed and corruption at the highest levels and business as usual in this province.Our ex-premier Gordon Campbell (a.k.a Scambell) is Bilderberger scum who was recently "rewarded" with a post as British High Commissioner for his services in stealing the provinces resources. His equally corrupt brother is heavily-invested in these Frankenfish farms and now both levels of govt. are threatening the biologists to shut them up about the lethal virus and where it came from. Sadly typical of how things are run up here (and all over it looks like.)

You got to be fucking kidding, the BC coast used to be covered in factories processing salmon for global sales, the harbors were full of boats catching salmon, every man and his dog were out at weekends, catching salmon. And now they have a fucking inquiry into where they have all gone???These government assholes couldn't put 2+2 together without getting 5. I'll give you a clue.........WE ATE THEM ALL, EVERY FUCKING ONE OF 'EM.

I should add that the river referred to here runs right by my window so I take an interest in it and have been following this for years. Overfishing and increasing water temperatures are partly to blame but most of the devastation appears to be due to this virus, to which wild salmon have no natural immunity. Millions of salmon simply fail to return to the rivers to spawn which suggests that they are dying at sea. A year or two ago we had a large run but most years lately have been poor.
